Hotronic's XLP PFI 50 socks are integrated with Hotronic's heating elements allowing for maximum toe warmth and blood circulation. Designed with a wool blend, these socks wick moisture while keeping your feet warm and cozy. Hottronic utilizes BootDoc's Power Fit Technology to create a relatively gradual pressure distribution to enhance performance. These socks function as an additional set of heat socks or as a replacement pair to be used with your Hotronic XLP One battery.
